Abstract
Stability of a ferrofluid flow in an annular region between two co-axially rotating porous cylinders with a radial flow in the presence of an axially applied magnetic field has been investigated numerically. Magnetic field perturbations have also been considered in the ferrofluid in the annulus, and it has been found that for all values of the radial Reynolds number \Rn, the flow is stabilized by the applied magnetic field. The stability characteristics have been found to depend heavily upon the radius ratio ξ of the cylinders. Figs 11, Refs 18.
